tests: Remove ignored parameters from push notifications tests.

Removes `token_kind` parameter being passed to
`remove_apns_device_token` and `remove_android_reg_id` code
paths / endpoints. Possibly missed in a refactor of this
function as the tests for adding these tokens do not pass
a `token_kind` parameter.

Removes `zulip_org_id` and `zulip_org_kay` from code testing
`deactivate_remote_server`. These parameters are passed when
a remote server is added, so possibly a copy and paste error
when these tests were written / last refactored.
